Can I use an 02 fuel rail on my 03 Ecotec? Will it fit right up?

I seem to remember reading somewhere that the 02 Ecotecs had different injectors than the 03 up Ecotecs.

most of the 02s had different injectors and rails than the 03+ ecotecs. the last bunch of 02s, i believe, had the 03 style rail and injectors. i know that my 02 had different injectors and thats the reason why the supercharger kit for the 02 comes with the necessary lines, rail and injectors to convert to the 03 setup

whats wrong with your current fuel rail? or are you just looking to pick up a spare to paint or polish and then swap right in?
